Abstract
Description
- This application claims priority of German patent application no. 10 2018 001 702.9, filed Mar. 3, 2018, the entire content of which is incorporated herein by reference.
- The invention relates to a function module for an electronic access control to a housing for electrical equipment, wherein electronic built-in modules such as control modules, monitoring modules, switching modules or the like are arranged in the housing. The built-in modules are connected to a common data bus, wherein a built-in module is connected to an interface over the data bus. The built-in module is accessible through the interface for the exchange of data.
- A large number of built-in modules that are to be serviced electronically by corresponding data processing programs are installed in known housings, in particular in the case of switch cabinets in electrical installations and the like. Data access to the individual built-in modules is possible via an interface in order, for example, to update an individual built-in module and/or to call up, change or delete data. Firmware updates are, moreover, in most cases necessary for built-in modules with microprocessors in order, for example, to fix bugs, security loopholes or the like.
- For data access, for example, to a switch cabinet, it must be opened, for which purpose the operating person must carry a mechanical key. It is disadvantageous that the operating person must—when servicing a plurality of switch cabinets—often keep various mechanical keys ready. In addition, an opening of the switch cabinet is usually not recorded, and there is therefore a possibility of manipulations.
- It is an object of the invention to provide an access control system with various security levels for industrial use, with which a secure authentication and recording of a service person accessing the switch cabinet is possible.
- The object is achieved with a function module wherein a blocking module is provided between the interface and the data bus which, when the blocking module is in a disable state, restricts or interrupts the traffic on the data bus and, when the blocking module is in an enable state, enables the data bus for a preferably unrestricted data exchange between the interface and the built-in module.
- For an access to the housing and/or for a data access to the built-in modules in the housing, the service person must thus switch the blocking module into the enable state. This is done via a control unit that actuates the blocking module which is configured as a switch, in particular as an electronic switch. The blocking module is connected for this purpose via a control line to the control unit. The control unit is advantageously configured such that it only actuates the switching module after checking an authentication such as, for example, an access code, and its verification. The service person can thus only access the switch cabinet after authentication and/or after verification of an access code. The function module is advantageously configured as a common structural unit together with the control unit and the blocking module.
- The control unit in particular includes a microprocessor that controls the communication to and from the control unit and verifies the authentications that are communicated. Such microprocessors store respective work records on the basis of which it is possible to establish which service person, at what time, to what extent and over what period of time had access to the housing or its built-in modules.
- It is provided in a preferred form of embodiment that the control unit provides the authentication such as, for example, an access code, over a network. For this purpose the control unit is connected to the network, which can take place wirelessly or—preferably through the interface—via cable. After input of the necessary access data at an in particular mobile PC, the control unit expediently communicates with the web server for authentication. After verification of the received authentication, the control unit enables the blocking module. An in particular unrestricted communication between the interface and the built-in modules is enabled.
- In an embodiment, the control unit is connected with at least one reading device for an authentication such as an access code. This reading device can be a card reading device, an RFID reading device, an NFC reading device or a similar reading device. The function of a reading device can be a component of the described invention.
- It can also be advantageous for the control unit to be connected to a keyswitch. The keyswitch serves for the authentication, wherein, after actuation of the keyswitch, the control unit switches the blocking module into the enable state.
- In a further embodiment, it is provided that the control unit is connected via a control line to an electromechanical locking apparatus for a door of the housing. A mechanical access control for the manual access to the built-in modules in the housing can in this way also be provided through the function module, so that a mechanical access is only opened to particular, qualified service persons.
- It can be provided that the interface is provided inside the housing and/or outside the housing. An external interface can be provided in a wall of the housing, preferably in a side wall of the housing. This is made possible in a simple manner through the installation of appropriate built-in sockets, accessible from outside, such as SUB-D, RJ45, USB or similar sockets.
- In a further embodiment, it is expediently provided that the enable state and/or the disable state of the blocking module is indicated by an in particular visual display.
- The invention will now be described with reference to the drawings wherein:
-

The built-inmodules 6, which in the embodiment are thecontrol module 8, themonitoring modules 9 and theswitching modules 12, are connected together via an, in particular common,data bus 13. Thedata bus 13 connects aninterface 14 to the built-inmodules 6, and enables a communication of each individual built-in module with theinterface 14. - The
interface 14 can be arranged as aninternal interface 14 a within thehousing 1. Theinternal interface 14 a is only accessible after opening thehousing 1. Expediently, it can be anexternal interface 14 b which—as suggested inFIGS. 1 and 2 —can be provided in aside wall 15 of thehousing 1, for example. Theexternal interface 14 b is accessible from the outside when thehousing 1 is closed. - The
interfaces 14 can be configured as USB interfaces, as RJ45 interfaces as sub-D interfaces, or the like. In the embodiment shown, USB interfaces 16 a and 16 b are provided both for theinternal interface 14 a as well as for theexternal interface 14 b. The USB interfaces 16 a, 16 b are implemented as aUSB socket 16, known per se. - The
internal interface 14 a and/or theexternal interface 14 b can further include RJ45 interfaces 17 a and 17 b. Advantageously the RJ45 interfaces 17 a and 17 b are implemented asRJ45 sockets 17. - Fundamentally, a
single USB socket 16 or asingle RJ45 socket 17 is sufficient as aninternal interface 14 a and/orexternal interface 14 b. In the embodiment shown, theinternal interface 14 a has fourRJ45 interfaces 17 a and threeUSB interfaces 16 a.

internal interface 14 a and also anexternal interface 14 b are provided. It can be sufficient to provide only oneinternal interface 14 a orexternal interface 14 b. - The built-in
modules 6 of thehousing 1 are connected via thedata bus 13 to theinterface 14. A blockingmodule 20 is provided between theinterface 14 and thedata bus 13. The blockingmodule 20 is implemented as aswitch 18 in the embodiment shown, in particularly as an electronic switch. - In the embodiments shown according to
FIGS. 2 and 3 , the blockingmodules switch interface 14 and one or a plurality of the built-inmodules 6 is interrupted. In the disable state of the blockingmodule 20, no data exchange is possible via theinterface 14 with the built-inmodules 6. The blocking module is in the disable state when not powered, so that data access to the built-inmodule 6 is blocked in the event of a power failure. - The blocking
module 20 is controlled via acontrol line 21 from acontrol unit 22 in order to change the switch state. Thecontrol unit 22 is advantageously configured to check an authentication such as, for example, an access code. - The authentication, made by way of example in the form of an access code, can be provided to the
control unit 22 via a network connection, in particular a LAN connection. A LAN connection can be established in an easy manner via an external orinternal RJ45 socket 17. - It is preferably provided that a data access to the
control unit 22 is enabled via theinternal interface 14 a and/or theexternal interface 14 b independently of the switch state of the blockingmodule 20. In this way it is possible—both in the disable state of the blockingmodule 20 as well as in the enable state of the blockingmodule 20—for thecontrol unit 22 to communicate with a web server via a wired or wireless network connection. If the web server—after the input of access data by a service person—communicates a valid authentication to thecontrol unit 22, this will close theswitch 18 and transfer theblocking module 20 into the enable state. The enable state of the blockingmodule 20 is suggested inFIG. 2 by the dashed line. - Thus if the
control unit 22 receives a valid authentication, for example an access code, the blockingmodule 20 is actuated via thecontrol line 21; theswitch 18 changes from the disable state into the enable state, which is suggested by the dashed line. In the enable state, thedata bus 13 is connected to theinterface 14, so that data exchange is possible between theinterface 14 and one or a plurality of the built-inmodules 6. A service device, for example, a laptop or the like, connected via theinterface 14 can call up, change or delete the data of the built-inmodule 6, and/or update the microprocessor installed in a built-in-module with firmware and/or call up stored log data. - In addition to transmitting an authentication via a network connection to the
control unit 22, the authentication can, also or alternatively, be transmitted via areading device 23 of thecontrol unit 22. Thecontrol unit 22 is connected for this purpose with at least onereading device 23. The reading device can be acard reading device 24 and/or anRFID reading device 25. Other types of reading device, for example, an NFC (Near Field Communication) reading device are also expedient. - In a simple form of embodiment, the
control unit 22 can be connected to akeyswitch 26 which—through closing one or a plurality of contacts—outputs a corresponding authentication to thecontrol unit 22. - It can be expedient to indicate the switch state of the blocking
module 20, for which purpose adisplay 27 can be provided. In the embodiment shown, a visible display from a state indicator for the switch state of theswitch 18 is provided. Afirst LED 28 can thus signal the disable state and asecond LED 29 the enable state of the blockingmodule 20. - The
internal interface 14 a and/or theexternal interface 14 b, the blockingmodule 20, thecontrol unit 22 with the reading device is 23 and/or thekeyswitch 26, as well as thedisplay 27, are preferably arranged in acommon function module 10 which is to be built into thehousing 1 or theswitch cabinet 2. Since all the elements necessary for the function are arranged in thefunction module 10 in a common construction unit, thefunction module 10 can be built into a housing, switch cabinet or the like without a high wiring effort. Thefunction module 10 is, in particular, suitable for retrofitting to existingswitch cabinets 2. - The
control unit 22 can, further, unlock theelectromechanical locking apparatus 5 of thedoor 3 of theswitch cabinet 2 via thecontrol line 11. To open theswitch cabinet 2, a service person connects a service device (mobile PC or the like) via anexternal interface 14 b, and communicates with thecontrol unit 22 which is accessible via a data connection, independently of the switch state of the blockingmodule 20. After transmitting a valid authentication, thecontrol unit 22 unlocks thelocking apparatus 5, so that theswitch cabinet 2 opens and all the built-inmodules 6 are mechanically freely accessible for a service. - In order to be able to actuate the
blocking module 20 without opening theswitch cabinet 2, areading device 23′, which can be configured, for example, as an RFID reading device, NFC reading device or similar contactless reading device, can be arranged, for example in theside wall 15 of the housing. A service person establishes a connection to theexternal interface 14 b via a service device, for example, a PC, and identifies themselves to thereading device 23′ via a corresponding chip or similar identifying element. Thecontrol unit 22—after verifying a valid authentication—will transfer theblocking module 20 into the enable state; the service person can carry out necessary service work without opening theswitch cabinet 2. In the embodiment according toFIG. 2 , thedata bus 13 is itself connected to theinterface 14 via theblocking module 20. In the embodiment according toFIG. 3 , thedata bus 13 leads to one or a plurality of fixedinterfaces 114, as shown inFIG. 3 . These interfaces can, for example, be anRJ45 interface 117 a or a USB interface 116 a. - In the embodiment according to
FIG. 2 , amains connection 30 for the supply of voltage to a service device, for example, a mobile PC, is furthermore provided. Themains connection 30—expediently together with a safety device—is in particular integrated into thefunction module 10. - The
function module 10 according toFIG. 3 is configured in such a way that theRJ45 interface 117 a can be connected via afirst blocking module 20 a to theinternal interface 17 a, while the USB interface 116 a is connected via ablocking module 20 b to theinternal USB interface 16 a. According toFIG. 2 , theinterface 14 provided is either aninternal interface 14 a and/or anexternal interface 14 b. Both theinternal RJ45 interface 17 a and also theexternal RJ45 interface 17 b are connected via a data line directly to thecontrol unit 22, so that—independent of the switch state of the blockingmodule 20 a—a direct data access to thecontrol unit 22 is provided both via theinternal RJ45 interface 17 a as well as via theexternal RJ45 interface 17 b. - Accordingly the
internal USB interface 16 a and/or theexternal USB interface 16 b are connected—in particular via separate data lines—to thecontrol unit 22, independently of the switch state of the blockingmodule 20 b. - The rest of the structure of the
function module 10 corresponds to that ofFIG. 2 , for which reason the same reference signs are used for the same parts. - In the embodiment according to
FIG. 3 , theinternal RJ45 interface 17 a and/or theexternal RJ45 interface 17 b can be activated separately from an activation of the USB interfaces 16 a, 16 b. An activation of theinternal USB interface 16 a and of theexternal USB interface 16 b is accordingly possible, independently of the RJ45 interfaces 17 a and 17 b. - The
function module 10 according toFIG. 3 is in particular advantageous as a retrofitting set for existing switch cabinets. It can also be expedient to permit a restricted data access to the control unit through the interface. Independently of the disable state or the enable state of the blocking module, at least the electromechanical locking of the door of the housing can be operated. - It is understood that the foregoing description is that of the preferred embodiments of the invention and that various changes and modifications may be made thereto without departing from the spirit and scope of the invention as defined in the appended claims.
